A new scheduler replaces the old one. - There are no sched_xxx_notify() calls that ask scheduler to change task state. - Tasks now have priorities and different timeslices. - One second interval is distributed among processes. - There are just runnable and expired queues. - SCHED_GRANULARITY determines a maximum running boundary for tasks. - Scheduler can now detect a safe point and suspend a task. Interruptible blocking is implemented. - Mutexes, waitqueues and ipc are modified to have an interruptible nature. - Sleep information is stored on the ktcb. (which waitqueue? etc.)
